Radiation risk for women in screening mammography examinations in Poland in 2007

摘要

Doses for women undergoing screening mammography examination should be as low as reasonably achievable, but compatible with the image quality necessary for an adequate diagnosis. The aim of this study was estimation of radiation risk according to "European guidelines for quality assurance in breast cancer screening and diagnosis" [1].Material for this study are the data from 250 screening mammography facilities. For every mammography facility standard average glandular dose for routine exposure were calculated. Furthermore, average glandular doses for individual mammography examination, according to the methods proposed by Dance and others [2], were calculated. Established average glandular doses in 250 mammography facilities range from 0.24 mGy to 15.2 mGy. At only 49 mammography facilities all expositions do not exceed acceptable levels of average glandular dose. At only 25 mammography facilities all expositions do not exceed achievable levels of average glandular dose. Obtained average glandular doses for women undergoing mammography screening examination reach alarming high values and they depend on technical parameters of mammography equipment.
